Sahih Muslim 2571a
'Abdullah reported: I visited Messenger of Allah ﷺ as he was running high temperature. I touched his body with my bard and said to him: Allah's Messenger, you are running high temperature, whereupon Messenger of Allah ﷺ said: Yes, it is so. I comparatively have a more severe fever than any one of you. I said: Is it because there is a double reward in store for you? Thereupon Messenger of Allah ﷺ said: Yes, it is so. And Messenger of Allah ﷺ again said: When a Muslim falls ill, his compensation is that his minor sins are obliterated just as leaves tall (in autumn). In the hadith transmitted on the authority of Zubair there is (no mention of these words):" I touched his body with my hands."
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَزُهَيْرُ بْنُ حَرْبٍ، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ الآخَرَانِ، حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ التَّيْمِيِّ، عَنِ الْحَارِثِ بْنِ سُوَيْدٍ، عَنْ عَبْدِ اللَّهِ، قَالَ دَخَلْتُ عَلَى رَسُولِ اللَّهِ ﷺ وَهُوَ يُوعَكُ فَمَسِسْتُهُ بِيَدِي فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّكَ لَتُوعَكُ وَعْكًا شَدِيدًا . فَقَالَ رَسُولُ اللَّهِ ﷺ " أَجَلْ إِنِّي أُوعَكُ كَمَا يُوعَكُ رَجُلاَنِ مِنْكُمْ " . قَالَ فَقُلْتُ ذَلِكَ أَنَّ لَكَ أَجْرَيْنِ فَقَالَ رَسُولُ اللَّهِ ﷺ " أَجَلْ " . ثُمَّ قَالَ رَسُولُ اللَّهِ ﷺ " مَا مِنْ مُسْلِمٍ يُصِيبُهُ أَذًى مِنْ مَرَضٍ فَمَا سِوَاهُ إِلاَّ حَطَّ اللَّهُ بِهِ سَيِّئَاتِهِ كَمَا تَحُطُّ الشَّجَرَةُ وَرَقَهَا " . وَلَيْسَ فِي حَدِيثِ زُهَيْرٍ فَمَسِسْتُهُ بِيَدِي .
